Fixed a bug when enabling framelock between displays connected to the
same GPU as other displays with different refresh rates, which caused the
latter to be incorrectly assigned to the framelock group.

Updated the reporting of HDMI 3D framerates and pixel clocks to be more
consistent with how they are reported by HDMI 3D displays.

Fixed a bug that sometimes prevented rotation controls in the nvidia-settings
control panel from working after changing resolutions.

Fixed a bug that could cause applications using GL_NV_vdpau_interop to
crash during modeswitches.

Fixed a regression that could cause OpenGL applications to crash while
compiling shaders.

Added a kernel module parameter, "NVreg_EnablePCIeGen3", which can be
used to enable PCIe gen 3 when possible. Note that on many systems where the
NVIDIA driver does not allow PCIe gen 3 by default, stability problems can
be expected when this option is enabled: users should do so at their own
risk.

Fixed a VDPAU bug that could cause the X server to hang when decoding
some corrupted video streams.
